Users (email accounts) are managed in `/tmp/docker-mailserver/postfix-accounts.cf`. **_The best way to manage accounts is to use the reliable [`setup.sh`][docs-setupsh] script_**. Or you may directly add the _full_ email address and its encrypted password, separated by a pipe:
In the example above, we've added 2 mail accounts for 2 different domains. Consequently, the mail server will automatically be configured for multi-domains. Therefore, to generate a new mail account data, directly from your docker host, you could for example run the following:
You will then be asked for a password, and be given back the data for a new account entry, as text. To actually _add_ this new account, just copy all the output text in `config/postfix-accounts.cf` file of your running container.
